Description

The NCP105 is 150 mA LDO that provides a very stable, accurate voltage with low noise suitable for space constrained, noise sensitive applications. In order to optimize performance for battery operated portable applications, the NCP105 employs the dynamic quiescent current adjustment for very low IQ consumption at no−load. The NCP105 is offered in both a small XDFN-4 1 mmx1 mm, 0.4mm Thin package as well as in a standard TSOP5 package.
